Abstract

An electric storage device management apparatus is provided for monitoring an electric storage device assembly including a plurality of electric storage devices connected in series. The apparatus includes a voltmeter, a discharging circuit, and a controller. The discharging circuit is configured to discharge the electric storage devices individually. The controller is configured to: determine whether a unit time variation in voltage of a first electric storage device has increased to a reference value and a unit time variation in voltage of a second electric storage device has increased to the reference value; measure an elapsed time period since the unit time variation of the first electric storage device has increased to the reference values and control the discharging circuit to discharge the electric storage devices based on the elapsed time period such that capacities of the electric storage devices are equalized.
